Features: 1. Latest M328 version of the software£¬ more functions. Chip: Atmega328 2.128x64 big Backlight LCD display£¬ only 2mA when stand by. 3. Using 9V battery (Not inlcuded) Test ranges: Inductors£¬ capacitors £¬ diodes£¬ dual diode £¬ mos£¬ transistor£¬ SCR £¬ the regulator£¬ LED tube £¬ ESR£¬ Resistance£¬ Adjustable potentiometer Resistance: 0.1 ohm resolution£¬ maximum 50M ohm Capacitor: 25pf -100£¬000 uf Inductors: 0.01mh-20H NEW Function: 1:Automatic detection of NPN and PNP transistors£¬ n-channel and p-channel MOSFET£¬ diode (including double diode)£¬ thyristor£¬ transistor£¬ resistor and capacitor and other components 2: Automatic test the pin of a component£¬ and display on the LCD 3:Can detect the transistor£¬ MOSFET protection diode amplification coefficient and the base to determine the emitter transistor forward biased voltage 4: Measure the gate and gate capacitance of the MOSFET threshold voltage 5:Use 12864 liquid crystal display with green backlight Specifications: For you reference 1£¬One -button operation£¬ automatic shutdown . 2£¬Only 20nA shutdown current. 3£¬Automatically detect NPN£¬ PNP bipolar transistors £¬ N -channel and P -channel MOS FET£¬ JFET £¬ diodes £¬ two diodes£¬ thyristors small power unidirectional and bidirectional thyristor. 4£¬Automatic identification components pin arrangement . 5£¬Measuring bipolar transistor current amplification factor and base - emitter threshold voltage. 6£¬Via the base - emitter threshold voltage and high current amplification factor to identify Darlington transistors. 7£¬Can detect bipolar transistors and MOS transistors protection diodes. 8£¬Measuring the gate MOS FET threshold voltage and the gate capacitance. 9£¬Can simultaneously measure two resistors and resistor symbol is displayed. Displayed on the right with a decimal value of 4 . Resistance symbol on both sides shows the pin number. So you can measure the potentiometer. If the potentiometer wiper is not transferred to an extreme position £¬ we can distinguish the middle and both ends of the pin. 10£¬Resistance measurement resolution is 0.1 ohms £¬ 50M ohms can be measured . 11£¬Can measure capacitanceCan measure capacitance of 30pF-100mF £¬ resolution 1pF. 12.2uF more capacitors can simultaneously measure the equivalent series resistance ESR values. The two can be displayed with a decimal value £¬ resolution 0.01 ohms. 13£¬Can be in the correct order and the diode symbol display two diodes £¬ and gives the diode forward voltage. 14.LED is detected as a diode forward voltage higher . Combo of the LED is identified as two diodes. 15£¬Eeverse breakdown voltage is less than 4.5V Zener diode can be identified. 16£¬Can measure a single diode reverse capacitance. If the bipolar transistor connected to the base and collector or emitter of a pin £¬ it can measure the collector or emitter junction reverse capacitance . 18£¬can be obtained with a single measurement rectifier bridge connection. Notice: Before measuring capacitance £¬ the capacitor must be discharged £¬ otherwise very likely damage the meter
